There are several reasons. First, mitochondria have a capsule around them very similar to bacterial capsules. Second, mitochondria are the only organelles in animal cells with their own genetic material. Third, mitochondria replicate themselves. Fourth, mitochondria are genetically similar to some bacteria.
What else can I help you with?
How do scientists think mitochondria originated?
Scientists believe that mitochondria originated from ancient bacteria that were engulfed by early eukaryotic cells through a process called endosymbiosis. Over time, the relationship between the host cell and the engulfed bacteria became mutually beneficial, leading to the evolution of mitochondria as specialized organelles responsible for energy production in eukaryotic cells.
Where do scientists believe mitochondria and chloroplasts originated?
Some scientists believe that mitochondria and chloroplasts were at one time independent-living bacteria that were engulfed by eukaryotic cells, forming an endosymbiotic relationship. This is because both mitochondria and chloroplasts have their own DNA and replicate themselves within the cells in which they occur.
What is found in mitochondria and chloroplasts that is not found in any other organelle except the nucleus leading scientists to believe that these two organelles are actually ancient prokayotes?
Mitochondria and chloroplasts contain their own DNA, separate from the cell's nuclear DNA. This unique DNA is circular, similar to bacterial DNA, leading scientists to hypothesize that these organelles were once independent bacteria that were engulfed by a precursor to eukaryotic cells in a symbiotic relationship.
Why do scientists believe that mitochondria may have been invaders of early cells?
Scientists believe this because DNA is found in mitochondrion, like a nucleus, and are also used in cells to create energy using ATP (adenosine triphosphate). Mitochonrion are very similar to prokaryotes, or cells with no nucleus- like bacteria. It is because of this reason that some scientists think that they originated from endosymbiotic prokaryotes. These are prokaryotes that live within another cell. They hypothesise that mitochondrion entered other cells, then gradually began to function FOR the cell, carrying out processes like the host cell's own organelles. Sorry if this is dodgy or anything, I've only just learnt this stuff. :)
Scientists think that plants evolved directly from what kingdom?
Scientists believe that plants evolved directly from a freshwater green algae called charophyte. There are two different types of charophytes, coleochaetales and charales, which strongly resemble earliest land plants.

How do scientist know that the first organisms were simple unicellular organisms?
Scientists data can only date back to when these simple, unicelluar organisms lived and thus believe other living organisms evolved through them.

Some organisms that appear to be very different from other organisms are in fact quite similar anatomically Scientists believe whales evolved from land mammals for many reasons including a few intern?

What do scientist think mitochondria used to be?
Scientists believe that mitochondria were originally free-living bacteria that were engulfed by larger cells in a process called endosymbiosis. Over time, the relationship between the two evolved into a mutually beneficial symbiosis, with the mitochondria providing energy to the host cell in exchange for a protected environment.

What is mitochondria's organ?
I believe you are confused. Mitochondria are organelles within (all) your cells.

Scientists believe the first photosynthetic organisms may have been cyanobacteria. This is believed because the biochemical pathways in the unicellular cyanobacteria.
